Description

technical field [0001] The invention relates to an intelligent hydraulic station, in particular to an intelligent hydraulic system for ensuring smooth oil supply and oil return of an electric spindle or other dynamic and static pressure functional components, and capable of real-time monitoring of lubricating oil supply and oil return. Background technique [0002] In the existing dynamic and static pressure lubrication electric spindle system, it is necessary to provide lubricating oil with a certain pressure, and pump this pressure lubricating oil from the oil tank to the electric spindle lubrication channel to form a pressure-bearing oil film, and then the lubricating pressure oil returns to the main shaft through the oil return pump. At the same time, a certain pressure of cooling oil is pumped from the oil tank to the cooling channel of the electric spindle to take away the heat generated during the operation of the electric spindle in real time, through the pressure dif...

AI Technical Summary

Problems solved by technology

[0003]Usually, because the fuel tank cannot be absolutely sealed, after a period of work, it is easy to mix granular debris into the fuel tank

When the hydraulic station is working, the particles are easy to accumulate in the precision filter, and then blockage will affect the normal operation of the hydraulic system

However, in actual processing, especially in milling and grinding, the entire system needs to run for a long time, and the oil supply failure of the hydraulic system is not allowed

[0004]In addition, due to the high-speed movement of the electric spindle, the temperature rise of the pressure lubricating oil is relatively large. At this time, the inertial force generated by the lubricating oil is also large, which leads to the delay in returning the lubricating oil The problem, which causes a large thermal error of the electric spindle
